GEORGE SLIDER, 0F BALTIMORE, MARYLAND.

WRINGER.

Application filed November 12, 1921. Serial No. 514,515.

To all whom it may concern:

Be it known that I, GEORGE Snrnnn, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Wringers; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it app-ertains to make and use the same.

My invention relates to wringers.

Among the objects of my invention are To provide a framework for a wringer which shall be inexpensive to construct, strong and handsome in appearance.

To provide a housing for the movable wringer roll and means for producing a pressure of said roll upon the fixed roll combined with improved means for immediately relieving the pressure of the movable roll from the fixed roll so as to obviate damage to the garments or injury to the operator in case the garments become caught on extraneous objects or the fingers of the operator are carried between the rolls.

These and further objects of my invention will he set forth in the following specification, reference being had to the accompanying drawings, and the means by which said objects are efi'ectuated will be definitely pointed out in the claim.

In the drawings:-

Figure 1 is a front view partly in section of my improved wringer.

Fig. 3 is an enlarged section along the line 3-3 in Fig. 1 looking in the direction of the arrows.

Fig. 4 is an enlarged section of the rolls and framework along the line 4--4: in Fig. 1 looking in the direction of the arrows.

Fig. 5 is a section on the line 5-5 in Fig. 3 looking in the direction of the arrows.

Fig. 7 is a section through the line 7-7 in Fig. 3 looking in the direction of the arrows.

Fig. 8 is a view pf the nut 33 looking in the direction of the arrow 8 in Fig. 7.

Fig. 9 is an enlarged view of the lower part of Fig. 1 looking in the direction of the arrow 9.

Fig. 10 is a view of some of the parts shown in Fig. 6 looking in the direction of the arrow 10 in said figure.

Fig. 11 is an enlarged vertical central section of the parts shown in Fig. 9.

The drip pan 10 is pivotally secured by the bolts 11-11 to the fixed bearing blocks 12-12 and the latter are secured in the guides 13-13 by the bolts 14-14. The bearing blocks 12-12 are provided with cylindrical bearings for the pintles 15 and 16 of the lower roll 17.

Sliding bearing blocks 18-18 are slidably mounted in the guides 13-13 and said hearing blocks are provided with cylindrical bearings for the pintles 19-19 of the upper roll 17.

'The guides 13-13 are bent around the bearing blocks 12-12 and the sliding bearing blocks 18-18 as shown at 20-20-20-20 in Figs. 1, 2 and 5.

For the purpose of holding the bearing blocks 12-12 and guides 13-13 in alignment and to support the means for producing pressure upon the upper roll, I provide the hollow frame 21 which has the similarly shaped sides 22-22 formed integrally with the end piece 23. The bearing blocks 12-12 and guides 13-13 are secured to the sides 22-22 by the bolts 14-14-14-1 1, which pass through said bearing blocks, guides and sides.

The sides 22-22 terminate at their right hand end in cars 25-25 which are secured by bolts 26 to the casting 27 forming part of the framework of the washing machine with which my improved wringer is usually combined.

The sides 22-22 are further secured to the casting 27 by bolts 28-28. Said casting supports the hollow frame 21 and it may also be provided with a bearing for the pintle 16. if desired.

The sides 22-22 are each provided with an opening 29, the lower edges 30 of which are formed by bending the metal of said sides inwardly upon itself, as shown in Fig. 4, in order to form a rounded edge to avoid injury to the garments, and also to provide additional strength for the lower edge of the opening 29 to support the pressure of the garments thereupon.

The upper roll 17 is pressed upon the lower roll 17 by the following instrumentalities z-The nut guide 31 is secured to the sides 2222 by bolts such as32 and the nut 33 slides freely in a hole provided in said guide, being prevented from turning therein by the pin 34 secured in the guide 31 and projecting into a slot in the nut. The pressure adjusting screw 36 is threaded in a hole in the nut 33 and said screw is turned by the arms 37. The lower end of the screw 36 is reduced and passes freely through a hole in the spring 38, a washer 39 being interposed between the body of said screw and the. top of said spring. A nut 40 prevents disengagement of said reduced portion from the spring 38. The ends of the spring 38 bear against the cross bar 41, the ends of which are secured to the sliding bearing blocks 1818 by screws as shown in Fig. 6. The cross bar 41 is in the form of a channel iron and the sides near the ends thereof are bent around'the end of the spring 38 as shown at 42, for a purpose hereinafter explained.

The upper end of the nut 33 is provided with a slot 43 for the reception of the detent 44 which works freely in a hole provided in the nut guide 31. Said detent is normally kept in engagement with the nut 33 by the. spring 45 which bears against the inner end of the safety lever 46 and normally presses the upper end of thearin 47 towards the left (see Figs. 1 and 7). The end of the arm 47 works freely in a slot provided in the detent 44. The safety lever is revolubly mounted on the right hand bolt 32 in a slot provided in the nut guide 31. The guides 13 13 are provided with holes 4848 and slots 4949 for clearance around the pintles 15 and 16 and 1919, respectively. The nut 33 is provided with a flange 51 for a purpose hereinafter explained.

The operation of my improved wringer is as follows The pintle. 16 is to be revolved in any approved manner and as the garments are passed between the rolls 17 and 17 the moisture ispressed out in the usual manner. Should the garments be caught upon any extraneous objects, or should the fingers of the operator pass between the rolls, by pressing downwardly upon the right hand end of the lever 46, the detent- 44 is withdrawn from the nut 33 in the direction of the arrow 50 and the downward pressure of the roll 17 instantly released, the flange 51 preventing the nut 33 from being thrown from disengagement with the guide 31. When it is desired to restore the parts to operative retion, it is necessary to turn the arms 37 in a counterclockwise direction, when viewed as in Fig. 2, in order to bring the nut to such a position that the detent 44 can again enter the slot 43.

he arms 37 are then to be turned in a clockwise direction to restore pressure of the upper upon the lower roll. 3

The bent-over portions of the bar 41 shown at 42 prevent separation of the sprin 38 from said bar, and also enable the operator to lift the upper roll 17 by turning the arms 37 in a counterclockwise direction.

It is to be noted that by the use of the hollow frame 21, preferably formed of sheet metal, 1 am enabled to provide an extremely light, strong and simple means for retaining the bearing blocks 12 in place and for affording a support for the nut guide 31.

It is also to be noted that by securing the bar 41 to the sliding bearing blocks 1818, I am enabled to keep the rolls 17 and 17 approximately parallel and also to provide for the lifting of the roll 17 by the operation of the arms 37.

lVhile I have shown one embodiment of my invention, it is to be noted that many changes may be made therein without departing from the spirit thereof.

It claim In a wringer, the combination with rolls having pintles and bearing blocks for said pintles, of a hollow frame for supporting said bearing blocks, a nut guide secured to said frame, a nut slidably mounted in said guide, a spring for producing pressure of one roll uponthe. other, a screw threaded in said nut for varying said pressure and a pin slidably mounted in said guide and entering a hole in said nut for locking said nut in fixed relation to said guide.

In testimony whereof, I affix my signature.
